When Hilton realizes that Griffin and Erica's friends are taking over his house -- watching his television and eating all his food, he decides that if they live in his house, Griffin and Erica will have to live by his rules. Reluctantly, Griffin and Erica agree to abide by Hilton's strict new set of house rules, including Rule #5 -- thou shall not alloweth men upstairs. So when Erica's boyfriend, Julius (guest star Darryl M. Bell, reprising the role), shows up in her bedroom, Erica attempts to keep it a secret from her father. Meanwhile, Hilton is busy on a mission to kill a stray mouse -- although Julius mistakenly believes that he is the target of Hilton's assassination plans. (thetvdb.com)
